EYEGLASSES.

Specification of Letters Patent.

Patented May 19, 1908.

Application filed October 19, 1906. Serial No. 339,624.

To all whom it may concern:

Be it known that I, LEO F. ADT, of Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Eyeglasses and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of the specification, and to the reference-numerals marked thereon.

My present invention relates to eyeglasses and has for its objects to provide a mounting particularly adapted for rimless glasses and embodying a rigid bridge to which the lens grips and nose guards are so connected that the guards may be separated for applying and removing the glasses from the wearers nose, by a movement of the lenses in a horizontal plane and the guards are permitted a yielding movement independently of the lenses, the movements of each guard and lens grip rela tive to one end of the bridge being controlled by a single spring which is readily applied and is of such nature that it is not liable to be unduly strained or its action impaired by continuous use.

It has further for its object to provide a mounting which is extremely simple in construction and operation and is quite inconspicuous, none of the operating parts being visible when the glasses are in position upon the wearers nose.

To these and other ends the invention consists in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings: Figure 1 is a front elevation of a pair of eyeglasses embodying my invention. Fig. 2 is a plan view. Fig. 8 is a rear elevation. Fig. 4 is a plan view of the glasses when in position on the wearers nose. Fig. 5 is a plan view showing the manner of separating the nose guards by the forward movement of the lenses. Fig. 6 is a sectional view on the line of Fig. 1. Fig. 7 is a perspective view of one end of the bridge. Fig. 8 is a similar view of one of the lens grips, and Fig. 9 is a similar view of a nose guard.

Similar reference numerals in the several figures indicate similar parts.

The lenses 1 are of the usual construction having at their inner proximate edges lens grips or clamps 2 provided in the present instance with the usual perforate lugs 3 ex. tending over the faces of the lenses and with the central arched portion adapted to extend over the wearers nose and to rest thereon and the extensions 6 forming ways or guides in rear of the attaching lugs of the lens grips and preferably in substantially the same horizontal plane as the latter. Between the arched portion and the extensions or guides 6 of the bridge, there are provided forwardly extending lugs or arms 7 to which the lens grips are pivotally connected, these pivotal connections being preferably in line with the lens edge and formed in the present instance by screws or pivot pins 8 passing through and secured to suitable apertures in lugs 9 on the lens grips and loosely through the per' forations 10 in the arms 7 on the bridge. The lugs 9 on the lens grips are elongated toward the rear of the lenses and form arms 11 extending transversely of the bridge extensions their inner proximate sides abutting the lower ends of the arch which form stops limiting the movement of the lenses on the pivots and maintaining them in alinement, as shown in Fig. 3. The outer sides of the arms 11 are inclined slightly, as shown at 12, forming seats for the plates 13 forming part of or attached to the nose guards 14, and apertured for the passage of the extended ends or guides on the bridge which passes through them.

15 indicates small coil springs encircling the guides on the bridge, abutting the guard plates 13 at one end and at their outer ends confined by suitable means such as nuts 16 applied to the threaded ends of the bridge extensions.

The nose guards may be of any suitable configuration, but I prefer to make them of a single piece of flat sheet metal reinforced by or integral with, the plates 13 and having the lower loops 17 and the upwardly and rearwardly extending pads or arms 18. The apertures in the guards or plates through which the guides pass, are large enough to not only permit the guards to slide freely longitudinally thereon when they are separated by the forward movement of the lenses as in Fig. 5, but also to permit the guards to yield independently of the bridge and lenses and grip the wearers nose by spring pressure, as shown in Fig. 4.

The operation of the mounting will now be readily understood, the normal position of the parts being as shown in Fig. 2, the springs holding the guards against the arms 9 and the latter against the stops formed by the lower ends of the arched portion of the bridge. To apply the glasses the outer ends of the lenses are tilted forwardly, as in Fig. 5, and the guards moved outwardly on the bridge ends against the tension of the springs and widely separated for application to the wearers nose, the movement of the lenses on the bridge being limited by suitable stops such as the lugs 19 which engage the forward edges of the lens gri s in the present construction. When the g asses are properly positioned the lenses are released and the sprin s pressing on the guard plates not only hold the guards yieldingly against the nose of the wearer, but also hold the forward edges of the guard plates 13 against the arms 11 of the lens grips, and the latter against the stops formed by the arched portion of the bridge so that the lenses are maintained in proper alinement, although the guards are permitted an independent yielding movement to accommodate themselves to the nose, as shown in Fig. 4.

While the particular construction of the holding pads on the guards is not essential to the operation of my mounting, it is desir able that they be offset somewhat from the plates 13, as by means of the supporting arm 21, so that their bearing surfaces or pads may form substantial continuations of the inner surface of the arch or saddle portion of the bridge, thus allowing the latter to come in contact with the wearers nose and form a more secure bearing for the glasses.

By arranging the springs on the extensions of the bridge and in rear of the attaching lugs of the lens grips all of the operating parts of the mounting are concealed when the glasses are in position on the wearers nose, thus rendering the glasses particularly sightly in appearance. The employment of two plain spiral springs for holding the lenses in position relative to each other and to the ridge, and also to hold the guards with a yielding pressure on the nose, materially simplifies the construction and enables the parts to be readily assembled by unskilled operators.

I claim as my invention:

1. In an eyeglass mounting, the combination with the bridge, of a lens grip pivoted thereto, a noseguard movable on the bridge a connection between the grip and the nose guard to cause the guard to move on the ridge with the grip and also to permit the guard to move independently of the grip and a single spring controlling the relative movements of the bridge, lens grip and guard.

2. In an eye lass mounting, the combination with the bridge, of lens grips pivoted thereon, the opposing noseguards movable on the bridge a connection between the grip and the nose guard to cause the guard to move on the bridge with the grip and also to permit the guard to lnove independently of the grip and a single spring arranged between each end of the bridge and the corresponding nose guard and operating through the latter upon the lens grip.

3. In an eyeglass mounting, the combination of a bridge, lens grips pivoted thereon, longitudinally compressible coil springs mounted on the bridge and connection between the lens grips and the springs causing the compression of the springs when the grips are turned in one direction, and the movement of the grips in the other direction when the springs expand.
